Hello aspirant!

Since have mentioned that you have got 64964 rank in jee mains open category and you are willing to take admission EC branch in HBTU since HBTU consider JEE Mains rank for admission in various engineering branches

As you might be aware that HBTU has not declared its cutoff for 2019 session till now

So with the  help of previous year cutoff you can have a fair idea about your admission chances

As per 2018 cutoff

Final round:

Branch.                    Closing rank

EC.                                25922

Since your obtained rank is very much more than the required rank so you cannot expect your admission in HBTU  in EC branch

Hopefully I have resolved your query
